The New Zealand dollar traded in a narrow range as investors look for signals indicating when the US Federal Reserve is likely to start tapering its stimulus programme.

The kiwi edged up to 83.75 US cents at 8am in Wellington from 83.63 cents at the 5pm market close on Monday, having traded in a tight 37 basis point range overnight. The trade-weighted index advanced to 77.94 from 77.86.

The Fed last week unexpectedly chose not to pare back its $US85 billion ($NZ101.62 billion) monthly bond buying programme as it awaits more data showing a sustained revival in the world's largest economy. A reduction in the money printing programme is supportive of the US dollar because it would reduce the volume of the currency in circulation, boosting its value.

"The currency is looking for offshore direction and that offshore direction has got to come around US moves and US moves then define back to taper or not taper," said Alex Sinton, senior dealer at ANZ New Zealand. "Until there is more directional bias out of the US it would be hard to call a build onto recent moves or a reversal of some of the gains."

A report on US revised second quarter GDP scheduled for release on Thursday may provide some direction, Mr Sinton said.

The local currency advanced to 62.06 euro cents from 61.81 cents after European Central Bank president Mario Draghi told the European Parliament he is ready to offer banks more long-term loans if needed. Germany's election may also be weighing on the euro because Angela Merkel's conservatives will likely have to convince left-wing rivals to join them in government.

The New Zealand dollar was little changed at 88.66 Australian cents from 88.72 cents, was at 52.18 British pence from 52.21 pence and it slipped to 82.70 yen from 82.88 yen.
